1 Communications Group Our group is one of the 8 research groups in the Electrical and Computer Engineering i Department t

2 Communications Group The research interests of the communications group fall into four broad categories: Information/Communications Theory Wireless Communications Communication Networks Digital Signal Processing

3 Communications Group 18 Professors Parham Aarabi (cross - Computer Group) Raviraj Adve Brendan Frey Dimitris Hatzinakos Ashish Khisti (New 2009) Frank Kschischang Raymond Kwong (cross Control Group) Alberto Leon-Garcia Ben Liang Jorg Liebeherr Teng Joon Lim (Graduate Coordinator) Hoi-Kwong Lo (cross - Physics) Pas Pasupathy (Emeritus) Kostas Plataniotis (Chair) Elvino Sousa Shahrokh Valaee Tas Venetsanopoulos (Emeritus) Wei Yu Parham Aarabi (cross Computer Group) Over 120 Graduate students and visitors Ph.D. 50% M.A.Sc. 30% M.Eng. 20%

4 Undergraduate Courses Responsible for teaching: Signal Processing (e.g. ECE216); Probability (e.g. ECE302); Communications (e.g. ECE316); Networks (e.g. ECE361).

5 Graduate Students Admissions (commgrp) Admissions (ECE) M.A.Sc. Ph.D. M.Eng M.A.Sc. and Ph.D. are research-based degrees; M.Eng. is course-based. Large segment of ECE graduate student population. Office and lab space mostly in Bahen, but some are in other buildings.

6 Application Process At end of 4F term: prepare application material e.g. transcripts, CV, research statement; t t Talk to professors about their research areas, and decide which one(s) appeal to you; Ask professors if they are taking new students (sometimes they don t). Submit application before deadline. Follow up with favourite professor!

7 Program Requirements M.A.Sc. Thesis proposal at end of 1S term; Thesis defense approx. end of 2 nd summer. Ph.D. Qualifying exam, middle of 1S term; Thesis proposal, p middle of 2F term; Yearly progress review with thesis comm.; Thesis defense (whenever supervisor tires of you!)

8 Information/Communications Theory Information theory: classical and quantum Channel coding and modulation Probabilistic and Statistical Inference Professors: Brendan J. Frey Ashish Khisti Frank R. Kschischang T. J. Lim Hoi-Kwong ong Lo Wei Yu From gene expression data to prediction of gene function

9 Wireless Communications Fading channels Diversity e.g. multi-antenna (MIMO) Mobility Handoffs between cells, channel estimation & tracking, synchronization problems High data rate, many users Multi-user interference problems, efficient resource allocation vital Ubiquitous coverage Cooperative networks Dynamic spectrum access, cognitive radio. Professors: Elvino Sousa Teng Joon Lim Raviraj Adve Source Destination Relays

10 Communication Networks Network Architectures: application-oriented oriented architecture, autonomic service architecture, service overlay networks Network Protocols: differentiated services, mobile Internet protocols, photonic-label switching, peer-to- peer networking Network Management: multimedia networking, wired/wireless integration, radio spectrum management, mobility management Theoretical Foundations: network calculus, queuing analysis, traffic modeling, game theory, learning mechanisms Wireless Networking: wireless broadband access, cognitive radio, sensor/ad hoc networking, wireless mesh networks, wireless local area networks, vehicular communication Professors: Alberto Leon-Garcia Ben Liang Jorg Liebeherr Shahrokh Valaee

11 Digital Signal Processing Image and Video Processing Digital Camera Processing cdna Micro-array Imaging Visual Object Compression Universal Multimedia Access Multimedia Security Authentication & Fingerprinting Image and Video Encryption Visual Secret Sharing Secure Streaming Watermarking Biometrics & Surveillance Face Recognition Gait Recognition Visual Surveillance Professors: D. Hatzinakos R. Kwong K. N. Plataniotis

12 Technology Sectors Communications technology impacts many sectors of economy: Wireless networks: 3G, Wi-Fi, WiMax, 3GPP-LTE. Provides convenient connectivity to Internet from anywhere. Information security: cryptography, watermarking, biometric i authentication. ti ti Internet and telephony infrastructure: networks operated by service providers such as Bell Canada, Rogers, Telus. Automobiles: vehicle-to-vehicle communications, intelligent t highways. h
